Patented Dec; 31, 1912.

Application filed September 19, 1811. Serial No. 650,112.

To all whom it may concern:

Be it known that I, SETH C. CATLIN, a citizen of the United States, residing at Bloomfield, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Carboy-Rockers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as' will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

.This invention relates to an improved carboy rocker which is adapted to be used for tiltingcarboys so as to permit the safe and easy pouring of a liquid from the carboy.

The rocker is adapted to be fixed to the side of a carboy and to be tilted, and has means thereon for grasping the carboy so that when the rocker is tilted the carboy comes with it, and is easily handled even when full.

The carboy rocker is made with rocker arms which have curved surfaces on which the device is rocked, these surfaces being of large radii, these radii intersecting at about the middle of the rocker arms so that the rocker arms are widest at the center, and when the rocker is swung to one side or the other of the center it has a normal tendency to retain the position in which it is placed. As the carboy becomes emptied, the distribution of its weight permits it to be held by the rocker in positions that require. very little tilting to bring the fluid in the carboy to the outlet spout.

The invention is further designed to provide a rocker of this kind which is quickly secured to a carboy and which is provided with rollers so that it can be used as a truck to shift the carboy from one place to another with slight effort.

The invention is illustrated in panying drawing, in which- Figure 1 is a side -view of a device showing the method of attaching it to a carboy. Fig. 2 shows the position of the rocker and the carboy when the carboy is about half empty. Fig. 3 is a similar view showing the carboy nearly empty, and Fig. 4 is a back view of the accomthe rocker.

The device is adapted to be used on the usual type of carboy having the outside wooden casing 10 inclo'sing a flask or bottle 11, and this being heavy and sometimes containing acid which when spilled is dangerous and destructive, it is unwieldy.

My invention consists of a rocker to be fixed to the carboy by which the carboy is easily handled, the rocker consistingv of rocker arms 12 which are separated and connected by suitable connecting strips 13.

At the bottom of the carboy are the supporting hooks 14 which can be attached to the rocker in any suitable manner, but I prefer to provide these hooks with the upturned ends 15 which penetrate slightly into the casing 10 of the carboy and take a firmhold on the casing. A retaining hook 16 is arranged near the top oft-he rocker and is adapted to engage the carboy near the top to hold the rocker and the carboy close together. The hook is usually formed on a bar 17, the hook being bent up from the bar, the bar sliding in the rockeri and being normally forced toward the hooks .14 by a spring 18 which is fastened at one end on the rod, and is fastened at the other end to the rocker, preferably to the pin 19 of one of the connecting strips. The bottoms of the rocker arms are beveled as at 20, these beveled portions being provided with rollers 21, and it will be obvious that when the device is tilted slightly it rests on the rollers- 21 alone and can be used as a truck. The rollers are placed near the ends of the beveled portions farthest from the front of the arms.

When the rocker is to be fastened to a-carboy it is placed alongside the carboy and the carboy slightly raised, and then the supporting hooks 14- can be passed under the carboy and the carboy allowed to rest on the supporting hooks. The hook 16, while it slides, is also rotatable so that if necessary it canl be swung back out of the way when the carboy is being placed on the supporting hooks 14, then the hook 16 is pulled up by hand, the rocker securely seated against the side of the carboy, and then the hook released to permit the spring 18 to drive it into the wooden casing of tl-.,'car' boy, or it can be forced in by hand, and the rocker is then seated alongside the caaboy as shown in Fig. 1, and as described before when slightly tilted, the rocker can be used as a truck to move the carboy about.

The front faces of the rocker arms are curved to give-it a rocking motion, these formed in a curve of large radii as at 2'3,

and from the widened center the face of each arm is curved with a large radius as at 24 down to the beveled bottom 20. The curves 23 and 2 1 intersect at about the center of the rocker arms the intersecting surfaces being, rounded. I i

NVhen the carboy and its rocker are tilted so that the corners 25 engage the floor, the carboy is not tilted enough to cause or permit any liquid from flowing from the neck or outlet of the carboy, and the carboy is not tilted sufliciently to permit any of its material to be extracted by pouring until a part ofthe curved surface 24 engages the floor. The rocker arms support the weight of the carboy, and it is necessary for the operator to exert very little strength on the carboy to regulate the distance it is tilted, and it is easily swung back 1:10 an upright position when it is desired to When the carboy and its rocker are tilted so that the corners 25 and the rollers engage the floor, the-carboy is held in this position ready for further tilting so that it is not -necessary when the carboy is nearly full to always return it to its flat position on the floor, but it is held in this half-way tilted position which makes the labor of giving it a further tilting motion very light.

Fig.2 shows the position of the rocker and the carboy when the carboy is about half empty, and the carboy will assume this normal position, that is, a position at which no liquid emerges from the neck of the carboy, and it must be tilted slightly forward to cause any liquid to flow, and when released, it sinks backto the position shown in Fig. 2, thereby doing away with any dripping from the neck of the carboy. As the carboy becomes emptied more and more, it assumes the position shown in Fig. 3, the weight of'the liquid being toward the neck of the carboy and normally forcing the carboy to assume the position shown in Fig. 3 so that the carboy need be tilted but slightly to pour liquid from the carboy.

It will be understood that to drain the carboy it must be tilted farther than shown in Fig. 3, but this tilting is easy, since the weight of the carboyf1s supported on the hooks, and the carboy being nearly empty,

it is naturally lighter and can be easily handledw 1 j I do not wish to be limited to the exact form of supporting hooks and the retaining lneans illustrated anddescribed, as I may use different forms without departing from the invention.

' It will be seen from this description that the carboy can be held sitions by the rocker. First, on the 'rollers and the corners 25, then on the surfaces 24,

and in the third position, on the surfaces 23, and moved. with the utmost ease from one to the other, thus providing for three positive positions and making .it easy to assume the alternate intermediate positions.

Having thus described my invention, what I claim is 2-- 4 1. A carboy rocker consisting of rocker arms, each rocker arm having its front face curved 'with two surfaces of large radii which intersect at approximately the centers of the arms, the intersections of the surfaces being rounded, the arms tapering toward their ends, the bottomof each arm being beveled, and a roller on the beveled portion of each arm, the rollers being situated near the end of the beveled portion farthest from the front of the arms.

2. A carboy rocker consisting of rocker arms, each rocker. arm having its front face curved with two surfaces of large radii iiv'hich intersect at approximately the centers of the arms, the intersections of the surfaces being rounded, the arms tapering toward their ends, the bottom of each arm being beveled, a roller on the beveled portion of each arm, the rollers .being situated near the endof the beveled portion farthest from the front of the arms, supporting hooks on the bottom of the arms, connecting strips between the rocker arms, a bar sliding in the connecting strips, said bar being bent at its upper end into a retaining hook, and .a spring bearing on one of the connecting strips and on the bar for forcing the hook in engagement with 'a carboy.
